The return movement of the handle or 'crank 3 is properly arrested by n. stop 12 secured on the frame of the 11( machine and against which the arm on the handle shaft bears when it is in normal posi tion.

The operation and advantages` of the in- 5 vention will be clear from the foregoing dcscri tion andthe drawing. -f

ile the invention has been described as ap lied to an adding machine and as particular y adapted for such use it will be seen that it is adapted for use with other classes of machines adapted to be acti'iated by a 'swinging or' rocking handle and including parts, o ersted, by and connected with said hand e, which may move at a different rate of speed from that imparted to the handle or crank.

What 1 clarin, is

l. The combination of a shaft, an operating handlie connected iixedly therewith, a working s ft, and connections between the two shafts having bearings arranged to make eontactrto insure the movement of one shaft with tha other in moving the in one direction, one bearing spported to yield under pressure of 'the handle and to permit independent movements of the handle and connections when the handle is moved in the other direction.' A

2. The combination of a shaft an operat I ing handle connected xedly therewith, a- 130 working shaft, connections between the two shafts having bearings arranged to make contact to insure the movement of one shaft with the other in moving' the handle in one direction, but capable of separation to permit independent movements when the handle is moved in the other direction, and adetent arranged to afford a limited resista'nce to the said inde endent movement. 3. The combination o a working shaft, a

40 swi han le controlling the movement of the shaft and connections between the handle and shaft includinga slotted link and a pin moving with the handle and extending into Athe slot in said link and a yielding bearing for said pin. .carried bythe linlgwhereby the -shaft will be positively rocked in one direction by swinging the handle but the -latter' under pressure may move in the w'op te direction without operating-said v 4.. The combination of a working shaft,

handleving handle; means independent of thea swinging handle, means independent oi the handle controlling the movement of the shaft, andI connections between the handle and shaft including n slotted. link connected with the shaft, a pin movable with the handle and extending into the slot in said link, and av pivotally mounted abutment carried by theflink and normally engaging said pin, substantially as and for the purpose described.

5. The combination of a Working shaft,

e; swinging handle, means independent of the handle controlling the movementl of the shaft, and connections between the handle 4and shaft including a slotted link connected with the shaft, a pin movable with the handle and extending into the slot in said link and a pivotall 'mounted s ring actuated abutment carried by the lin and normally en aging said pin, substantially as and for t iepurpose described. 6. The combination in an ad ding machine, of e, working shaft, a counter-shaft connected to move in unison with the working shaft, a swinging handle, means independent of the handle controlling the speed of xnovement of said shafts, and connections between the counter shaft and handle, including a ielding member, whereby said shafts will e positivel moved in one direcf tion by swinging the handle but the latter may be moved in a reverse direction against the resistance of the yielding member but is normally held in position by the latter.

7. The combination of a working shaft and means for limiting its spoed of rotation an o erating shaft and handle connecte fixed y therewith, and devices including a link intermediate the two shafts for com municating movement from tho handle shaft to the working shaft, said devices constructed to normail reserve the relation of the handle and liidi gut to ield under the movement of the handle sha t in one direc- 'tion at a speedin excess of that of the working shaft.
